Being a solid material, polyamide powder has the attractive feature of being self-supporting for the generated product sections. This makes support structure redundant. Polyamide allows the production of fully functional prototypes or end-use parts with high mechanical and thermal resistance. Polyamide parts have excellent long-term stability and are resistant against most chemicals. They can be made watertight by impregnation. The PA material used by Materialise is certified as biocompatible and food-safe under certain conditions.

Unfinished parts typically have a grainy surface but all kinds of fine finishes are possible. PA 12 parts can be sandblasted, colored/impregnated, painted, covered and coated.

How Does Laser Sintering Work?

Laser Sintering is a laser-based technology that uses solid powder materials, typically plastics. A computer-controlled laser beam selectively binds together particles in the powder bed, by raising the powder temperature above the glass transition point after which adjacent particles flow together. As the powder is self-supporting, no support structures are necessary.
